[PATCH] wifi: rtw89: coex: set higher priority to BT when WL scan and BT A2DP exist

[Ping-Ke Shih]

From: Ching-Te Ku <ku920601@realtek.com>

If WiFi operation channel & scan channel both at 2.4GHz, original will keep
going at WL > BT priority table for a long time. It makes A2DP can not sent
audio data to SUT device in time then performed a lag audio. Assign
a BT > WL priority table when A2DP exist, to avoid the issue.
